Kubernetes, Easy (Beginner), Concepts. https://k8wiz.com/uquiz/what-happens-when-you-apply-a-resource-that-already-exists-in-the-cluster

- A. The existing resource is deleted and recreated
- B. The operation fails with an error
- C. The existing resource is updated with the new configuration
- D. A new resource is created with a different name

**Answer:** The existing resource is updated with the new configuration

**Explanation:** When you use 'kubectl apply' on a resource that already exists, Kubernetes will update the existing resource with the new configuration, applying only the changes. This is part of the declarative approach to resource management in Kubernetes.
